What this book covers

Chapter 1, Getting Started with LED Programming through Raspberry Pi GPIO, helps you learn the basics of the Raspberry Pi GPIO and LED development so that you can be sure that you have the basics required to develop LED programming through Raspberry Pi GPIO.

Chapter 2, Make Your Own Countdown Timer, explains how to work with 7-segment displays and build a countdown timer. The basics of 7-segment display programming will be introduced. Furthermore, you will learn what shift register is and how to use it to enhance the handling of several 7-segment display modules.

Chapter 3, Make Your Own Digital Clock Display, explores how to build a digital clock. A digital clock is a type of clock that displays the time digitally using 4-digit 7-segment display modules. Furthermore, you will learn how to work with an OLED graphic display through an I2C interface and how to use it to build a digital clock.

Chapter 4, LED Dot Matrix, describes how to control an LED dot matrix with Raspberry Pi. At the end of the chapter, you will cascade several LED dot matrix modules and build a program to operate those modules.

Chapter 5, Building Your Own Traffic Light Controller, explains, in detail, how to build a traffic light controller using Raspberry Pi, from designing to implementing. Controlling AD/DC lamps using channel relay is introduced too.

Chapter 6, Building Your Own Light Controller-based Bluetooth, describes, in detail, how to build a light controller-based Bluetooth in a Raspberry Pi board. You can control the LEDs, lamps, or other devices from any device with a supporting Bluetooth stack, such as Android.

Chapter 7, Making Your Own Controlled Lamps through Internet Network, helps you make your own controlled lamps through the Internet network. You can control your LEDs, lamps, or other devices from any device with a supporting Internet network stack by utilizing RESTful. You will also learn how to build mobile application using PhoneGap and control LEDs from your mobile applications.
